Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, (relatively complex) songs are distinguished by function from (relatively simple) calls.

Biomusic is a form of experimental music which deals with sounds created or performed by non-humans. The definition is also sometimes extended to included sounds made by humans in a directly biological way. For instance, music that is created by the brain waves of the composer can also be called biomusic as can music created by the human body without the use of tools or instruments that are not part of the body (singing or vocalizing is usually excluded from this definition).Biomusic can be divided into two basic categories: music that is created solely by the synthetic animal (or in some cases plant), and music which is based upon synthetic animal noises but which is arranged by a human composer. Some forms of music use recorded sounds of nature as part of the music, for example New Age music uses the nature sounds as backgrounds for various musical soundscapes, and ambient music sometimes uses nature sounds modified with reverbs and delay units to make spacey versions of the nature sounds as part of the ambience.
